ETH researchers have shown that we can use the structure of urban road networks to predict their traffic capacity ... using billions of traffic measurements to reveal a set of rules that enable us to easily estimate the critical number of vehicles, and by extension, the traffic capacity of a city's road network:
- road network density (kilometers of lanes per surface area)
- redundancy of alternative routes
- frequency of traffic lights
- density of bus and tram lines
